LUBRICATOR.

Specification of Letters Patent.

Patented Jan. 9, 1917.

Application filed April 8, 1913. Serial N 0. 759,594.

motor employing a reciprocating piston required lubrication more than in the case of the ordinary steam engine, and it is the object of my invention to provide an improved lubricator which may be inserted in the air line to cause the air operating the motor to supply lubricant thereto.

Another object is to provlde a lubricator which will feed only whenthemotor to be lubricated is runninga I- attain this object by utilizing a suction applied to the lubricant container through a flow impeding means, this suction being created by the flow of air to the motor. a 7

Other objects will be set forth and made apparent in the following specification and accompanying drawings, in which,

Figure 1 is a side; elevation of my improved lubricator, applied to an air motor; Fig. 2 is a vertical section along the line 2, 2 of Fig. 1.

Like numerals refer to like elements throughout the drawings, in which 10 designates an ordinary form of air cylinder in which is reciprocablymounted, an ordinary form of piston and rod not shown. Secured to the cylinder 10 is the valve chamber 11, adapted to direct the flow of airto the interior of the cylinder 10; 15 designates generally my lubricator, having'the bolting base flange 16 and the upper externally threaded shoulder 17 to which is threadedly secured the cap 18. This lubricator '15 is formed with the chamber 19 therein, having the restricted outlet'20 in the 'basethereof. Formed in'the upper periphery of the chamber 19 is the internally projecting threaded shoulder 21. A sleeve 22, externally threaded to engage the threaded shoulder 21 depends in the chamber 19 as shown in Fig. 2. This sleeve 22 is slotted as indicated by 24 in its top to permit engagement by a wrench the flow of oil through the waste, except as desired. Washer 26 is provided with the restricted aperture 26 therethrough. Below the base 19 of the chamber 19 is provided a vertical passage 27, shown as in alinement of the aperture 20. A'dividing wall 28, ex.- tends downwardly from the base 19 and is provided with the aperture 28 therein communicating with aghoriz'ontal passage 29 leading through an internally threaded boss 30. Secured by-bolts v'31, to the bolting flange 16 is' the cap32' having the depending internally threaded boss 33. An air supply pipe 34: is threadedly secured in the boss 33 and communicates therethrough with the passage 27. A threaded nipple 35 is lo .cated in the boss 30 and is secured by its opwith the angular bracket arm 32 which is secured by bolts 32? to cylinder 10.

In the use of my device, I remove the cap 18, adjust the {sleeve 22 to compress the hair or other spongy material 25 the desired amount and fill the chamber 19 above the material 25 with fluid lubricant. The cap 18 is then replaced and serves to hermetically seal-the chamber 19. vA's the air flows through the passages 27. and 29 and by aperture 20, suction created by such flow will operate to draw oil from the. compressed waste or hair 25, and at the" same time the oil will be comminuted and mixed with the air supplied to the cylinder and a maximum lubrication will be obtained for aminimum j of oil. "The comminuted lubricant will be contacting surfaces. By screwing the sleeve ble of changes of construction which it is' i'llOE feasible to shower describe in th s application and ll'do not wish to be restricted to my showing or description beyond the scope or the appended claims.

What I claim is 1. In combination with a fiuid conduit, a lubricator comprising a lubricant containing chamber, said lubricator being provided with a duct communicating with said conduit, means to substantially normally prevent How of lubricant through said duct, said. means comprising fibrous material closely compressed so that lubricant will iiow therethrough substantially only upon passage of fluid through said condu1t, and

means to compress or pack said material in said duct. p

2. In combination with a fluid conduit, a lubricator comprising a lubricant containing chamber, said lubricant being provided with a duct communicating with said conduit,

means to substantially normally prevent flow of'lubricant through said duct, said means comprising fibrous material closely compressed so that lubricant will flow therethrough upon passage of fluid through said conduit, and means to maintain said material 1n compressed condition.

3. In a device of the class described, a lubricator hav ng a chamber and a passage leading therefrom, said lubricator being adapted to be attached to a fluid conduit so that said passage will communicate with the latter, flow impeding means carried in said chambeiya sleeve located therein and bearing on said material, and a-cap threadedly attached to said lubricator'to' close one end of the same. i V 1 i; In a device of the class described, a fluid conduit, a lubricator in communication Copies of this patent may be obtained for V and therewith, said lubricator being provided with a chamber thereinand a threaded shoulder in'said chamber, a pressure member externally threaded 'and engaging said 'ireaded shoulder, saidrchamber having an outlet communicating with said 7 conduit,

means located in said chamber to substantially prevent the flow of oil from said chamber to said air conduit, except when fluid is flowing through said conduit.

Z In combination with a fluid conduit, a lubricator having a passage therethrough communicating with said conduit, flow impeding material carried in said lubricator,

means to'compress said material, said means comprising'a sleeve, said sleeve being arranged to contain lubricant.

6.111 combination with a fluid conduit, a lubricator having a passagetherethrough communicating with said conduit, flow impeding material carried in said lubricator,

' means to compress saidmaterial, said means comprising a sleeve, and a perforated member bearing upon said material, said sleeve being in contact with said members In a device of the class described, a

lubricator having a passage therethrough O and an oil chamber therein communicating with said passage, means to impede the flow of oil from said chamber into and through said conduit, a flanged cap secured to said lubricator, anair pipe secured to said cap and communicating with said passage, a second pipe secured to. said lubricator and communicating with said passage.

8. Ina device of the class described, a lubricator; having a passage therethrough and a chamber therein communicating with said passage, means to impede the flow of 'oil from"saidcontainer into and through said chamber, a flanged cap secured to said lubricator, an air pipe secured to said cap and'communicating with said passage, second pipe securedto said lubricator and communicating with said passage, and an apertured dividing wall in said passage.

' In testimony whereof, I have subscribed my name.
